Solid BCG
This is a very well constructed, high-quality bolt carrier group. The only reason I gave it four stars instead of five is because of the price currently being asked for this fine bit of craftmanship. However, if money is not of concern for you, then you would be hard-pressed to buy a better bolt carrier group.

Well I said I would buy a
Well I said I would buy another one and so I did. This is a great BCG. High quality with no issues. I fired some PMC FMJBT, Lake City 5.56 and even some Silver Bear hollow points, fired every round without any issues. Clean up was a breeze, even after putting the silver bear hollow points through it. I cleaned it with Break Free bore and action cleaner, it was like new in minutes. I cant say enough about this Bolt Carrier Group.
